Computer Memory Solutions 8GB (2x4GB) DDR3 1333MHz CL7 SODIMM for HP Pavilion dm4 memory upgrade

HP Pavilion dm4 upgrade kit

This 8 GB kit contains two 4 GB DDR3 SO-DIMMs built for HP Pavilion dm4 entertainment notebooks. Each module runs at 1333 MHz with CL7 latency and 1.5 V unbuffered operation. The 204-pin form factor matches the factory slots exactly. Buyers who need more than 8 GB total capacity cannot use this kit.

Sustained throughput with CL7 timing

The modules operate at PC3-10600 speed with 7-7-7 timings for low latency during extended workloads. Major-brand chips and 2Rx8 organisation help maintain stability when the system runs for long periods. Systems based on Intel GL40 chipset will limit the memory bus to 1066 MHz regardless of module rating. Buyers who require ECC error correction must choose a different product.

DDR3 SO-DIMM interface limits

The DDR3 SO-DIMM standard tops out at 1333 MHz for this platform, so no higher frequency is possible. A 32-bit operating system caps usable memory at 4 GB even with both slots filled. Installing 4 GB modules may show only 3.5 GB depending on system configuration. Buyers who want faster memory technology must replace the notebook.
